Inspection systems corrugated

INSPECTION AT THE HIGHEST LEVEL

The Erhardt+Leimer Group has been using inspection cameras for guiding, web viewing and inspection technologies for over 30 years. The companies’ expertise ranges from hardware development of cameras controllers, trigger boards and lighting technologies, software development for detection algorithms, defect classifications and HMI interfaces, to application implementation and machine integration into varies processes of web and sheet fed industries. This expertise has now been integrated into the world of Corrugating by utilizing proven hardware and software packages and applying them to Corrugating Converting and machinery, such as Printing Machines, Die Cutters, Gluers and Folders as well as Inline Boxmaker machines. The applications range from Print Inspection of print quality, color drift, defects, hickies, scratches etc. “Print to Die Cut Accuracy”, Glue Application Inspection and Manufacturers Gap Inspection of the folded box.

Function

The OCS 1 has been developed with specific emphasis for harsh environments. Its IP 65 protection class guarantees the highest level of reliability. It has been specifically developed for image monitoring in applications were space is limited for vision systems.The ELSCAN monitor displays high resolution captured images immediately, with a speed up to 5 images/sec. The exact positions of the longitudinal and cross cut are captured and displayed on the monitor. Any deviations of the cut can be recognized directly on the first sheet – and not only by the machine operator at the down stacker of the corrugator. Furthermore the ELSCAN software offers various capabilities to work with the images, for example a measuring tool where two lines can be positioned horizontally and vertically on the screen using a mouse. The displayed distances can immediately be used to determined and monitor the cut to mark accuracy and quality. Especially the production of preprint becomes substantially more efficient by the application of the ELSCAN CORR OCS 1.

Function

The E+L PGS-CORR system is designed to automatically inspect complex shapes, print and die cut patterns to ensure repeatable quality of web or sheet processes. The high resolution color camera can be applied as a single fixed mounted sensing head, inspecting a defined area of interest or on a moving sensing support to enable the operation to sense area’s across a wide web or sheet width. Multiple camera head design and control algorithm can be applied to ensure quality in different areas of the repeat and/or with different tolerance settings at the same time. The control algorithm will compare the live scan with a pre-programmed master image (golden template) and log inaccuracies in reference to tolerances and thresholds that can be freely defined. Outputs for automatic rejection devices, alarm horns or alarms lights or even machine control signals can be defined as needed.
